Vela Supernova Remnant

Supernova Remnant in the southern constellation Vela is the closest remnant to Earth. It is “only” 800 light years away from us and it has a diameter of 100 light years. This is the reason why this deep space object didn’t fit in the field of view of my portable 250 mm focal length RedCat. The initial plan was to make a panorama of two pictures, but I failed to make an overlap, so I present two separate pictures. At least I have one more reason to come back to Namibia ,’-)

IC443 Jellyfish nebula

Jellyfish Nebula is a supernova remnant in the constellation Gemini. A very long time ago a supermassive star exploded and emitted a lot of material into space. It is not clear when exactly it happened, but the latest research dates the explosion between a few thousand years and 30’000 years. The shape definitely resembles a jellyfish, having the head at the top and tentacles at the bottom and overall it looks like it floats in the space. It’s interesting how many nebulae have names related to an animal. For example the Seagull Nebula, the Elephant Trunk Nebula, the Eagle Nebula, the Lobster Nebula, the Horsehead Nebula, etc.

M1 Crab nebula

It all started here. Crab nebula is the first catalogued deep space object. Charles Messier was searching for the comet (1758) but discovered his first deep space object. Crab nebula, also called Messier 1, is a supernova remnant – something like Veil nebula, but it’s much further from the Solar system – 6500 light years.

My first picture was made with pinched mirror, therefore I waited two years and captured it properly. Since I live in light polluted area, I chose narrow band filters, in order to get better contrast and composed this picture out of hydrogen alpha (red channel) and OIII (green and blue channel) narrow band pictures.

NGC6992 Veil nebula

The mostly photographed deep space object by me is Veil nebula. I simply love this supernova remnant. Previous mosaic picture revealed that the eastern part is slightly brighter, therefore I pointed my telescope with longer focal length there and made this bi-color picture.

NGC6960 NGC6992 Veil nebula mosaic

Here is another picture of my favorite Veil nebula. First attempt here with long focal length (1000 mm), second attempt here with shorter focal length (730 mm) and finally third here with the shortest focal length I have (430 mm). Still I haven’t captured everything of the nebula last year and this year I focused my smallest telescope to the western part of the Veil nebula and created mosaic.

The picture, as well as the previous ones is bi-color images. I captured hydrogen alpha (Ha) and oxygen III (OIII) narrow band images and inserted Ha image into the red channel and OIII into green and blue channel.
